Sterilization of men and women is the most popular method of contraception in Canada. The contraceptive effect of a vasectomy usually occurs within 3 months. The production of sperm, however, is not interrupted, and an increase in pressure proximal to the ligation site may cause rupture of the epididymis or the ductus deferens, with extravasation of spermatozoa and the formation of granulomas or sperm antibodies. Increased pressure may also explain the postvasectomy pain syndrome.
绝育是加拿大最受欢迎的避孕方法。输精管结扎术的避孕效果通常在3个月内显现。然而,精子的产生并未中断,结扎部位近端压力增加可能导致附睾或输精管破裂,精子外渗并形成肉芽肿或精子抗体。压力增加也可能解释输精管结扎术后疼痛综合征的原因。
